The structure at 85K is also reported (see #0.412). It has the same MSG but rather different moment orientations. The spin reorientation is reported to take place at about 55K.
The figure in the original reference is inconsistent with the moment components listed the article. The component values listed in the article have been assumed to be correct.
See #0.141 for a model of the same phase at 4.2K with important differences.
